In the event the licensee / prospective licensee or any of its subsidiaries has brought or asserts any claim for patent infringement against IBM or any of its subsidiaries, IBM has the right to unilaterally suspend, terminate, withdraw the offer or withhold the grant of the license / prospective licensee to the licensee and its subsidiaries.
